Introducing my timing light - injection timing- digital RIV method- bench test

[funola]

The FSM procedure 07.1-108, Checking injection timing (begin of delivery) with digital tester (RIV method) has a diagram which shows a setup of 3 pieces of hardware for checking injection timing.

The 3 pieces of hardware are:

617 589 10 2100 RI- Transmitter
617 589 09 2100 RI- Adapter (for available digital tester)
Bosch MOT 001.03 Digital tester

I have built my own system which provides the same functions as the above. Just did a bench test and took a short video.

On the left is a drill spinning a disc with a screw to simulate the tang behind the injection pump timing plug.

Clamped in the vise is the pickup (RI-transmitter)
The pickup is plugged into the RI- Adapter (The aluminum box) which outputs to an inductive timing light.
The digital tester is just a conventional inductive timing light.

The portable drill goes up to 1000 RPM. As you can see, tracking is spot on at all speeds! The strobe cutout you see is due to the drill not hard mounted relative to the pickup so the gap moved a bit as I operated the drill. I will be testing this in the car over the next few days and will shoot another video.
